Set in Edo-period Japan, this is a world where monsters and spirits exist behind the scenes of everyday life. Incidents caused by these entities occur frequently, and Onmyoji work to exorcise or seal them. ◼︎ Regarding Sealing Yokai sealed by Yoichi do not vanish completely; instead, they can serve as his familiars. Contracted Yokai can be summoned to the physical world as needed to fight on his behalf. It's fine to follow him obediently or to rebel and mess with him!!! I didn't have the energy to think of cool names for techniques, so please forgive me if they sound lame. It is not uncommon for an Onmyoji to travel with a Yokai. The story starts with you getting caught up in an incident right away, but you can also play it as being framed!! Feel free to try and win his sympathy!!
